Manager Discussion of Fund Performance
To reflect strategy enhancements and broader diversification, the Fund was renamed as Columbia Multi Strategy Alternatives Fund effective August 1, 2019.
Columbia Management Investment Advisers, LLC (CMIA) serves as the investment manager for the Fund and attempts to achieve the Fund’s objective by managing a portion of the Fund’s assets and selecting one or more subadvisers to manage other sleeves independently of each other and CMIA. Effective September 24, 2019, subadvisers AQR Capital Management, LLC (AQR) and QMA LLC (QMA) each began managing a portion of the Fund. As of May 31, 2020, CMIA, AQR and QMA managed approximately 50.3%, 25.5% and 24.2% of the portfolio, respectively.
For the 12 months that ended May 31, 2020, the Fund’s Class A shares returned -6.58% excluding sales charges. To compare, the FTSE One-Month U.S. Treasury Bill Index returned 1.57% and the HFRX Global Hedge Fund Index returned 2.95% over the same time period. As an absolute return fund, it employs a benchmark agnostic strategy and therefore comparisons to the FTSE One-Month U.S. Treasury Bill Index and the HFRX Global Hedge Fund Index are for information purposes only.
Market overview
The annual period ended May 31, 2020 saw a market environment that enjoyed positive absolute returns in many asset classes through its first eight months. Then, fears of the rippling effects of the global COVID-19 pandemic on the economy, on corporate earnings and more began to impact investor sentiment and roil the markets in February 2020. The sell-off within the U.S. equity markets was swift, with the S&P 500 Index recording its fastest 30% decline in history, taking only 22 trading days from the record high it had reached on February 19, 2020. The steep drop was followed by a 12.82% gain in April 2020, the best monthly return for the S&P 500 Index since 1987 and a 4.76% gain in May 2020.
Within the U.S. equity market, there was a massive difference in performance between value and growth equities, with the Russell 1000 Growth Index posting a return of 26.25% as compared to the -1.64% return of the Russell 1000 Value Index for the 12-month period. International equities were weaker overall than U.S. equities. The MSCI EAFE Index (Net), representing developed international equities, posted a return of -2.81%, and emerging markets equities struggled even more, with the MSCI Emerging Markets Index (Net) generating a return of -4.39%.
As U.S. equities sold off in the first quarter of 2020, investors engaged in a “flight to quality,” and the fixed-income asset class overall outperformed equities both for the quarter and for the 12-month period. Indeed, more traditional fixed-income returns were among the best in the capital markets. The Bloomberg Barclays Global Aggregate Index, a broad proxy for the global fixed-income market, posted a return of 5.59% for the 12-month period, led by U.S. Treasuries. The Bloomberg Barclays Treasury Index rose 11.36% for the 12-month period. Securitized bonds and long maturity investment-grade corporate bonds also posted strong returns, as measured by the 6.02% return of the Bloomberg Barclays MBS 15 Year Index and the Bloomberg Barclays U.S. Corporate Bond Index, which returned 10.03%. In contrast, high-yield corporate bonds and emerging markets bonds, like equities, posted positive absolute returns through the first eight months of the period but then experienced significant losses. High-yield corporate bonds, as measured by the ICE BofA U.S. High Yield Constrained Index, edged out a 0.30% return and emerging markets bonds, as measured by the JPMorgan Emerging Markets Bond Index-Global, returned 1.65% for the period.
Returns of inflation-hedging asset classes were mixed. Real estate investment trusts (REITs) posted strong returns for the first eight months of the period but subsequently gave back those gains and more, resulting in a -14.55% return for the FTSE Nareit Equity REITs Index for the period. Commodities were also sharply negative, with the Bloomberg Commodity Index Total Return posting a -17.05% return over the annual period. Conversely, global inflation-linked bonds, measured by the Bloomberg Barclays Global Inflation Linked Bond Index (Unhedged), returned 5.73% over the one-year period.
Fund changes
At the start of the 12-month period, the Fund was managed entirely by CMIA. The Fund was transitioned from a core, liquid alternative risk premia-based strategy managed internally by CMIA, to a multi-manager strategy utilizing a combination of six different internally and externally managed alternative investment strategies. The strategies managed by AQR and QMA are global macro investment strategies, using a blend of quantitative and fundamental analysis and insights, with the aim of delivering strong risk-adjusted returns with low correlation to traditional asset classes.

Manager Discussion of Fund Performance  (continued)
CMIA: To begin the period, the Fund was 100% allocated to alternative beta strategies. Alternative beta strategies represent those strategies associated with the systematic risks embedded in capital markets and are driven primarily by: 1) academically-supported forms of risk premia (e.g., value, momentum or quality) and 2) investor-based behavioral biases, industry needs, structures and constraints (e.g., short volatility or commodity curve). In implementing these alternative beta strategies, the Fund maintains a multi-asset class, multi-style portfolio invested across specific risk premia styles in equity, fixed income, credit, currency, commodity and volatility-based strategies. Early in the period, however, we added three existing internal strategies to accompany a reduced weighting for the existing alternative beta strategy. These internal strategies were intended to represent approximately 50% of assets in our portion of the Fund’s portfolio:
1. The Mortgage Opportunities strategy runs in a manner substantially similar to Columbia Mortgage Opportunities Fund, utilizing the same process, strategy and portfolio management team. The strategy seeks total return, consisting of long-term capital appreciation and current income by investing across a broad spectrum of mortgage-related assets and asset backed securities, tactically allocating to high-quality agency mortgage-backed securities as well as higher yielding non-agency residential and commercial mortgage backed securities and asset backed securities, all based on a value-driven process.
2. The G10 Currency strategy carries a long-standing process that seeks positive absolute return. Returns result from income produced by short-term debt obligations and currency-linked derivatives based on value fluctuations of major foreign currencies relative to the dollar.
3. The Global Tactical Asset Allocation (GTAA) strategy is a rules-based, top-down multi-factor strategy designed to identify opportunities in liquid equity and fixed-income markets. It is intended to be non-directional to underlying traditional markets. The strategy is run by the Columbia Threadneedle Global Asset Allocation team using models that are based on over two decades of research.
Contributors and detractors
The Fund’s portfolio turnover for the 12-months ended May 31, 2020 was 789%.
CMIA: Several market factors contributed to our portion of the Fund’s negative performance during the 12-month period. The COVID 19 market sell-off, concerns related to Brexit (the U.K.’s departure from the European Union), low interest rates that were down over the year, negative commodity performance and negative market dynamics within the structured asset markets created a tough environment for our underlying mortgage strategy.
Our portion of the Fund had positive contributions from its G10 Currency strategy, which is a long/short quantitative currency trading strategy, as well as from its GTAA strategy. Strategies within our portion of the Fund that detracted from results during the 12-month period included the Alternative Risk Premia strategy, a multi-asset class, multi-style portfolio invested across specific risk premia styles in equity, fixed income, credit, currency, commodity and volatility-based strategies, and the Mortgage Opportunities strategy.
AQR: We began managing a portion of the Fund’s portfolio on September 24, 2019. From that date through May 31, 2020, our portion of the Fund’s portfolio underperformed the FTSE One-Month U.S. Treasury Bill Index and the HFRX Global Hedge Fund Index. Positive performance for the period was driven primarily by 2019 returns, particularly systematic equity and fixed-income strategies, which were largely driven by value factors. These gains, however, were offset in the first quarter by losses in our systematic developed equity strategies. The final two months of the period were positive, bringing overall performance for our reporting period to roughly flat, with asset level gains led by fixed income and equities.
Our Global Macro investment strategy seeks to deliver strong risk-adjusted returns that can be diversifying to both traditional and alternative investments. We believe that financial markets tend to underreact to changes in macroeconomic fundamentals. Our strategy tends to be positioned with long assets for which macroeconomic fundamentals are improving and short assets for situations where macroeconomic fundamentals are deteriorating. Macroeconomic trends are evaluated across multiple dimensions, utilizing both quantitative and discretionary inputs. We consider momentum, value, carry and defensive indicators of attractiveness, as well as other signals in security selection and trade in over 100 individual markets across approximately 30 countries.

Table of Contents
Manager Discussion of Fund Performance  (continued)
Among systematic views, notable contributors included developed yield curve strategies, particularly interest rate swap steepeners in the U.S. and U.K. against flatteners in the eurozone and Sweden, and emerging equity market strategies, particularly relative value long exposure to Korean equities and short exposures to Singaporean and Thai equity markets. From a factor perspective, value and momentum contributed to performance.
For discretionary views, positive performance came from positions spread across asset classes, such as fixed-income, currencies, equities and commodities. A discretionary U.S. steepened position added to returns as expectations for increased long-term bond issuance pushed up longer term Treasury yields. A steepened position is a strategy that uses derivatives to hedge against a widening yield curve. Discretionary trading benefited in the recent environment as defensive positioning initiated during the onset of the COVID-19 crisis became more positive on risk given the stimulus efforts from global fiscal and monetary authorities. The largest position-level contributors during our reporting period were short exposure to the Norwegian krone, short exposure to eurozone and Swedish 2-year interest rates and long directional exposure to U.S. equities.
Within systematic views, developed equity strategies were the largest detractors. Long positions in the eurozone and Spanish equities suffered losses as Europe became the epicenter of the COVID-19 pandemic in February and March 2020, resulting in equity market underperformance relative to other regions. A relative value short in Swiss equities also detracted, as that market’s defensive composition and large pharmaceutical weight drove relative outperformance. Tactical long positions in developed equity indexes detracted from returns in the first quarter of 2020 as the global spread of COVID-19 and associated economic disruptions led to a severe sell-off in global equities. From a factor perspective, carry (notably in fixed income and currency strategies) and fundamental momentum (mostly in equity strategies) detracted, partially offset by gains from value and momentum factors. The largest position-level detractors during the period were long exposure to Japanese interest rates, long exposure to German bonds and short exposure to Swiss equities.
The systematic components of our Global Macro investment strategy determine desired positions by processing large quantities of economic and financial data on a daily basis. This process is meant to capture both idiosyncratic changes in country-level fundamentals as well as broad shifts in the global economic environment. The emergence of COVID-19 in February and March 2020 impacted many quantitative signals, particularly those measuring trends in the business cycle, macro sentiment and monetary policy. These developments resulted in a shift toward more negative directional views on commodities and more positive directional views on fixed income.
Similarly, discretionary views responded to a number of qualitative catalysts during the period, but the emergence of the COVID-19 pandemic and associated economic impacts had the most profound influence on positioning, including a bearish view on U.S. equities in February, short views on crude oil in March and April, bearish views on the Canadian dollar and British pound in March and U.S. yield curve steepeners in March, April and May.
QMA: We began managing a portion of the Fund’s portfolio on September 24, 2019. From that date through May 31, 2020, our portion of the Fund’s portfolio underperformed the FTSE One-Month U.S. Treasury Bill Index and the HFRX Global Hedge Fund Index.
We believe that persistent return opportunities are generated by risk premia and mispricings. Further, we believe that a systematic framework using a mix of fundamental and market-based factors can identify those investment opportunities. We use a fundamental understanding of the drivers of returns to determine what we believe to be the most suitable set of factors for each asset class. We evaluate five factor categories (sentiment, valuation, risk/quality, growth and carry) across global equity markets, fixed income, currencies and commodities. In our Global Macro strategy, we have developed six independent absolute return strategies that seek to harvest these investment opportunities. We believe our approach is sustainable and robust consistent with the regular variable in prices relative to fundamentals that occur over a business cycle.
Our portion of the Fund’s portfolio underperformed during our reporting period, due to three components. The largest detractor was our relative value positioning within our Currency sub-strategy, which experienced losses on the New Zealand dollar, Canadian dollar and Norwegian krone. Our relative value Global Bonds sub-strategy also detracted, driven by our positioning in Canadian bonds. Carry and risk factor exposures experienced negative returns due mainly to the swift change in sentiment due to the COVID-19 pandemic. Finally, our portion of the Fund experienced negative contributions from our Directional sub-strategy, which takes views across asset classes, driven largely by positioning in equity markets.

Table of Contents
Manager Discussion of Fund Performance  (continued)
The Carry factor was the most consistent detractor to our portion of the Fund’s portfolio, having negative contribution in all sub-models where we use it as a factor (Bond Country Selection, Commodity Selection and Currency Selection). Bond Country Selection and Currency Selection also suffered from losses from our Risk factor. Commodity Selection also had negative contribution from the Sentiment factor. Equity Country Selection had losses from the Growth and Value factors. Our Directional sub-strategy suffered primarily from our Risk factor. The three biggest detractors from performance over the period were U.S. equity futures, Japanese equity futures and Canadian bond futures.
Our Commodity Selection sub-strategy benefited primarily from strong performance from the Risk factor, and the Currency Selection sub-strategy benefited most from the Value Factor. Our Directional sub-strategy and Equity Country Selection both had strong contributions from the Sentiment Factor. The three most significant positive contributors to performance over the period were gasoline futures, Canadian equity futures and Mexican equity futures.
Our Global Macro strategy employs approximately 60 macroeconomic, valuation and market-based inputs to inform our positioning. These include yield curve positioning, interest rates, credit spreads, cross asset class volatility measures, forecast economic growth and price trends, among others. During our reporting period, our inputs led us to take on an increasingly “risk on” position from the fourth quarter of 2019 through the middle of February 2020. Our positioning was beneficial during this time. The significant deterioration in market sentiment coincident with the onset of the COVID-19 pandemic in the second half of the first quarter of 2020 was detrimental to our performance given the "risk on" positioning. Our pivot to more defensive positioning, as informed by our inputs, resulted in positive performance in April and negative performance in May when risky assets rallied, shrugging off concerns about the COVID-19 crisis.
Derivatives usage
CMIA: Our portion of the Fund utilizes derivatives for both hedging and non-hedging purposes, including, for example, seeking to enhance returns or as a substitute for a position in an underlying asset or index. During the period, the Fund used tri-party swap agreements with a small group of approved counterparty bank providers to more efficiently and cost effectively manage its exposures. These flexible structures, which allow for direct and highly versatile portfolio management applications, detracted from the Fund’s results during the period.
AQR: Our Global Macro investment strategy is implemented using derivative instruments to generate economic exposures that target a certain level of volatility. Our portion of the Fund invests in liquid derivatives including global developed and emerging market exchange-traded futures, futures-related instruments, forward contracts and interest rate swaps across four major asset classes: commodities, currencies, fixed income and equities. It is our view that derivatives offer the most liquid, lowest cost and efficient way to gain diversified exposure across asset classes.
QMA: Our Global Macro strategy is 100% invested through derivatives.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Alternative investments cover a broad range of strategies and structures designed to be low or non-correlated to traditional equity and fixed-income markets and involve substantial risks and are more volatile than traditional investments, making them more suitable for investors with an above average-tolerance for risk. The Fund’s use of leverage allows for investment exposure in excess of net assets, thereby magnifying volatility of returns and risk of loss. Commodity investments may be affected by the overall market and industry- and commodity-specific factors, and may be more volatile and less liquid than other investments. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Foreign investments subject the Fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. The sales price the Fund (or its underlying investments) could receive for any particular investment may differ from the Fund’s (or underlying investments’) valuation of the investment. As a non-diversified fund, fewer investments could have a greater effect on performance. Frequent trading may result in taxable gains or higher transaction costs, reducing the Fund’s return. See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.

Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

* Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Fair value measurements  (continued)
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.
Forward foreign currency exchange contracts, futures contracts and swap contracts are valued at unrealized appreciation (depreciation).

Derivative instruments are valued at unrealized appreciation (depreciation).
(a) The realized gain (loss) earned during the period for Total Return Swap Contracts was $(32,350,729).
(b) Change in unrealized appreciation (depreciation) relating to securities held at May 31, 2020 was $(1,183,050), which is comprised of Asset-Backed Securities — Non-Agency of $(606,784) and Residential Mortgage-Backed Securities — Non-Agency of $(576,266).
The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain residential and asset-backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but were not limited to, observable transactions for identical or similar assets in the market and the distressed nature of the security. The appropriateness of fair values for these securities is monitored on an ongoing basis which may include results of back testing, manual price reviews and other control procedures. Significant increases (decreases) to any of these inputs would have resulted in a significantly higher (lower) fair value measurement.

Consolidated Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Note 1. Organization
Columbia Multi Strategy Alternatives Fund (formerly known as Columbia Alternative Beta Fund) (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Effective August 1, 2019, Columbia Alternative Beta Fund was renamed Columbia Multi Strategy Alternatives Fund.
Basis for consolidation
Effective September 24, 2019, CMSAF1 Offshore Fund, Ltd., CMSAF2 Offshore Fund, Ltd. and CMSAF3 Offshore Fund, Ltd. (each, a Subsidiary) are each a Cayman Islands exempted company and wholly-owned subsidiary of the Fund. Prior to September 24, 2019, CMSAF1 Offshore Fund, Ltd. (formerly known as CAAF Offshore Fund, Ltd.) was the sole Subsidiary. Each Subsidiary acts as an investment vehicle in order to effect certain investment strategies consistent with the Fund’s investment objective and policies as stated in its current prospectus and statement of additional information. In accordance with the Memorandum and Articles of Association of each Subsidiary (the Articles), the Fund owns the sole issued share of each Subsidiary and retains all rights associated with such share, including the right to receive notice of, attend and vote at general meetings of the Subsidiaries, rights in a winding-up or repayment of capital and the right to participate in the profits or assets of the Subsidiaries. The consolidated financial statements (financial statements) include the accounts of the consolidated Fund and each respective Subsidiary. Subsequent references to the Fund within the Notes to Consolidated Financial Statements collectively refer to the Fund and each Subsidiary. All intercompany transactions and balances have been eliminated in the consolidation process.
At May 31, 2020, the Subsidiary financial statement information is as follows:
  CMSAF1 Offshore Fund, Ltd. CMSAF2 Offshore Fund, Ltd. CMSAF3 Offshore Fund, Ltd.
% of consolidated fund net assets 0.00% 5.43% 2.87%
Net assets $17,132 $34,318,320 $18,110,890
Net investment income (loss) 475,370 93,426 58,029
Net realized gain (loss) (13,786,126) 1,526,380 3,400,555
Net change in unrealized appreciation (depreciation) 9,251,793 (475,158) (497,694)
The financial statements present the portfolio holdings, financial position and results of operations of the Fund and the Subsidiaries on a consolidated basis.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Consolidated Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.

Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.
Investments in open-end investment companies (other than ETFs), are valued at the latest net asset value reported by those companies as of the valuation time.
Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Option contracts are valued at the mean of the latest quoted bid and ask prices on their primary exchanges. Option contracts, including over-the-counter option contracts, with no readily available market quotations are valued using mid-market evaluations from independent third-party vendors.
Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.

Notes to Consolidated Financial Statements  (continued)
May 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Consolidated Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Consolidated Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Consolidated Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Consolidated Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Consolidated Statement of Assets and Liabilities.
Forward foreign currency exchange contracts
Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund’s securities, to shift investment exposure from one currency to another and to generate total return through long and short positions versus the U.S. dollar. These instruments may be used for other purposes in future periods.
The values of forward foreign currency exchange contracts fluctuate daily with changes in foreign currency exchange rates. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the forward foreign currency exchange contract is closed or expires. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without delivery of foreign currency.
The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund’s portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Consolidated Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to produce incremental earnings, to manage the duration and yield curve exposure of the Fund versus the benchmark, to manage exposure to movements in interest rates, to manage exposure to the securities market and to generate total return through long and short positions. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Consolidated Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Consolidated Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Consolidated Statement of Assets and Liabilities.
Options contracts
Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund purchased and wrote option contracts to protect gains and to manage exposure to fluctuations in interest rates. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain over-the-counter option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.
Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Consolidated Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.
For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.
Interest rate swaption contracts
Interest rate swaption contracts entered into by the Fund typically represent an option that gives the purchaser the right, but not the obligation, to enter into an interest rate swap contract on a future date. Each interest rate swaption agreement will specify if the buyer is entitled to receive the fixed or floating rate if the interest rate is exercised. Changes in the value of a purchased interest rate swaption contracts are reported as unrealized appreciation or depreciation on options in the Consolidated Statement of Assets and Liabilities. Gain or loss is recognized in the Consolidated Statement of Operations when the interest rate swaption contract is closed or expires.
When the Fund writes an interest rate swaption contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Consolidated Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the interest rate swaption contract written. Premiums received from writing interest rate swaption contracts that expire unexercised are recorded by the Fund on the expiration date as realized gains from options written in the Consolidated Statement of Operations. The difference between the premium and the

Notes to Consolidated Financial Statements  (continued)
May 31, 2020
amount paid on effecting a closing purchase transaction, including brokerage commissions, is also recorded as realized gain, or if the premium is less than the amount paid for the closing purchase, as realized loss. These amounts are reflected as net realized gain (loss) on options written in the Consolidated Statement of Operations.
Swap contracts
Swap contracts are negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the CCP in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Consolidated Portfolio of Investments and cash deposited is recorded in the Consolidated Statement of Assets and Liabilities as margin deposits. Unlike a bilateral swap contract, for centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the CCP stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Consolidated Statement of Assets and Liabilities.
Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Consolidated Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the FCM or CCP may not fulfill its obligation under the contract.
Credit default swap contracts
The Fund entered into credit default swap contracts to increase or decrease its credit exposure to an index. These instruments may be used for other purposes in future periods. Credit default swap contracts are agreements in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are generally defined as bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.
As the purchaser of a credit default swap contract, the Fund purchases protection by paying a periodic interest rate on the notional amount to the counterparty. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized loss upon payment. If a credit event as specified in the contract occurs, the Fund may have the option either to deliver the reference obligation to the seller in exchange for a cash payment of its par amount, or to receive a net cash settlement equal to the par amount less an agreed-upon value of the reference obligation as of the date of the credit event. The difference between the value of the obligation or cash delivered and the notional amount received will be recorded as a realized gain (loss).
As the seller of a credit default swap contract, the Fund sells protection to a buyer and will generally receive a periodic interest rate on a notional amount. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized gain upon receipt of the payment. If a credit event as specified in the contract with the counterparty occurs, the Fund may either be required to accept the reference obligation from the buyer in exchange for a cash payment of its notional amount, or to pay the buyer a net cash settlement equal to the notional amount less an agreed-upon value of the reference obligation (recovery value) as of the date of the credit event. The difference between the value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Consolidated Portfolio of Investments.

As a protection seller, the Fund bears the risk of loss from the credit events specified in the contract with the counterparty. For credit default swap contracts on credit indices, quoted market prices and resulting market values serve as an indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the contract.
Any upfront payments or receipts by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Consolidated Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.
Credit default swap contracts can involve greater risks than if a fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk.
Interest rate swap contracts
The Fund entered into interest rate swap transactions which may include inflation rate swap contracts to manage interest rate and market risk exposure to produce incremental earnings, to gain exposure to or protect itself from market rate changes, to synthetically add or subtract principal exposure to a market and to obtain long and short exposure to the total return on a reference index in return for periodic payments based on a fixed or variable interest rate. These instruments may be used for other purposes in future periods. An interest rate swap is an agreement between two parties where there are two flows and payments are made between the two counterparties and the payments are dependent upon changes in an interest rate, inflation rate or inflation index calculated on a nominal amount. Interest rate swaps are agreements between two parties that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future, based on a predetermined, specified notional amount. Certain interest rate swaps are considered forward-starting, whereby the accrual for the exchange of cash flows does not begin until a specified date in the future. The net cash flow for a standard interest rate swap transaction is generally the difference between a floating market interest rate versus a fixed interest rate.
Interest rate swaps are valued daily and unrealized appreciation (depreciation) is recorded. Certain interest rate swaps may accrue periodic interest on a daily basis as a component of unrealized appreciation (depreciation); the Fund will realize a gain or loss upon the payment or receipt of accrued interest. The Fund will realize a gain or a loss when the interest rate swap is terminated.
Total return basket swap contracts
The Fund entered into total return basket swap transactions. These instruments allow the Fund to manage exposure to a custom basket of securities and foreign markets (both long and short exposures) without owning or taking physical custody of such securities. Under the terms of the contract, payments made by the Fund or the counterparty are based on the total return of the reference assets within the basket in return for a specified interest rate. The contract allows the Investment Manager of the Fund to alter the composition of the custom basket by trading in and out of the notional reference security positions at its discretion.
The total return basket swap is valued daily, and the change in value is recorded as unrealized appreciation (depreciation). The swap resets monthly at which time the Fund settles in cash with the counterparty. Payments received (or made) by the Fund are recorded as realized gains (losses). Total return basket swaps are subject to the risk associated with the investment in the reference securities within the basket. The risk in the case of short swaps transactions is unlimited based on the potential for unlimited increases in the market value of the reference securities in the basket. The risk may be offset if the Fund holds any of the reference securities. The risk in the case of long swap transactions is limited to the current notional amount of the swap.

Total return swap contracts
The Fund entered into total return swap contracts to manage long or short exposure to the total return on a basket of reference securities in return for periodic payments based on a fixed or variable interest rate and to manage long or short exposure to the total return on a reference security index in return for periodic payments based on a fixed or variable interest rate. These instruments may be used for other purposes in future periods. Total return swap contracts may be used to obtain exposure to an underlying reference security, instrument, or other asset or index or market without owning, taking physical custody of, or short selling any such security, instrument or asset in a market.
Total return swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time the Fund will realize a gain (loss). Periodic payments received (or made) by the Fund over the term of the contract are recorded as realized gains (losses). Total return swap contracts are subject to the risk associated with the investment in the underlying reference security, instrument or asset. The risk in the case of short total return swap contracts is unlimited based on the potential for unlimited increases in the market value of the underlying reference security, instrument or asset. This risk may be offset if the Fund holds any of the underlying reference security, instrument or asset. The risk in the case of long total return swap contracts is limited to the current notional amount of the total return swap contract.

Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
To be announced securities
The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.
In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.
Mortgage dollar roll transactions
The Fund may enter into mortgage “dollar rolls” in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar but not identical securities (same type, coupon and maturity) on a specified future date. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund will benefit because it receives negotiated amounts in the form of reductions of the purchase price for the future purchase plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. The Fund records the incremental difference between the forward purchase and sale of each forward roll as a realized gain or loss. Unless any realized gains exceed the income, capital appreciation, and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund identifies cash or liquid securities in an amount equal to the forward purchase price.
For financial reporting and tax purposes, the Fund treats “to be announced” mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. These transactions may increase the Fund’s portfolio turnover rate. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.

Mortgage dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the counterparty may default on its obligations.
Interest only and principal only securities
The Fund may invest in Interest Only (IO) or Principal Only (PO) securities. IOs are stripped securities entitled to receive all of the security’s interest, but none of its principal. IOs are particularly sensitive to changes in interest rates and therefore subject to greater fluctuations in price than typical interest bearing debt securities. IOs are also subject to credit risk because the Fund may not receive all or part of the interest payments if the issuer, obligor, guarantor or counterparty defaults on its obligation. Payments received for IOs are included in interest income on the Consolidated Statement of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Consolidated Statement of Operations. POs are stripped securities entitled to receive the principal from the underlying obligation, but not the interest. POs are particularly sensitive to changes in interest rates and therefore are subject to fluctuations in price. POs are also subject to credit risk because the Fund may not receive all or part of its principal if the issuer, obligor, guarantor or counterparty defaults on its obligation. The Fund may also invest in IO or PO stripped mortgage-backed securities. Payments received for POs are treated as reductions to the cost and par value of the securities.

Notes to Consolidated Financial Statements  (continued)
May 31, 2020
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Consolidated Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared and paid annually. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Recent accounting pronouncement
Accounting Standards Update 2020-04 Reference Rate Reform
52 Columbia Multi Strategy Alternatives Fund  | Annual Report 2020

Table of Contents
Notes to Consolidated Financial Statements  (continued)
May 31, 2020
In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2020-04 Reference Rate Reform – Facilitation of the Effects of Reference Rate Reform on Financial Statements. This standard provides exceptions for applying GAAP to contract modifications, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The standard is elective and effective on March 12, 2020 through December 31, 2022. The Fund expects that the adoption of the guidance will not have a material impact on its financial statements.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The Investment Manager is responsible for the ultimate oversight of investments made by the Fund. The Fund’s subadvisers (see Subadvisory agreements below) have the primary responsibility for the day-to-day portfolio management of their portion of the Fund. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.96% to 0.93% as the Fund’s net assets increase. The effective management services fee rate, net of waivers, for the year ended May 31, 2020 was 0.89% of the Fund’s average daily net assets.
Prior to October 1, 2019, the Investment Manager had contractually agreed to waive 0.21% of the management fee.
Subadvisory agreements
Effective September 24, 2019, the Investment Manager has entered into Subadvisory Agreements with AQR Capital Management, LLC and QMA LLC, each of which subadvises a portion of the assets of the Fund. New investments in the Fund, net of any redemptions, are allocated in accordance with the Investment Manager’s determination, subject to the oversight of the Fund’s Board of Trustees. Each subadviser’s proportionate share of investments in the Fund will vary due to market fluctuations. The Investment Manager compensates each subadviser to manage a portion of the Fund’s assets.
In addition, the Fund’s Board of Trustees has approved a subadvisory agreement between the Investment Manager and Threadneedle International Limited (Threadneedle), an affiliate of the Investment Manager and an indirect wholly-owned subsidiary of Ameriprise Financial. As of May 31, 2020, Threadneedle is not providing services to the Fund pursuant to the subadvisory agreement.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Consolidated Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Consolidated Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
Columbia Multi Strategy Alternatives Fund  | Annual Report 2020

Table of Contents
Notes to Consolidated Financial Statements  (continued)
May 31, 2020
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended May 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.07
Institutional 3 Class 0.01
Class R 0.10
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Consolidated Statement of Operations. For the year ended May 31, 2020, no minimum account balance fees were charged by the Fund.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund, respectively.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended May 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 5.75 0.50 - 1.00(a) 3,128
Class C 1.00(b)
    
(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.

Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  October 1, 2019

Institutional Class 1.02 1.13
Institutional 2 Class 0.96 1.01
Institutional 3 Class 0.90 0.95
Class R 1.52 1.63
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Reflected in the cap commitments, prior to October 1, 2019, is the Investment Manager’s contractual agreement to waive 0.21% of its management fee.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At May 31, 2020, these differences were primarily due to differing treatment for trustees’ deferred compensation, derivative investments, tax straddles, late-year ordinary losses, non-deductible expenses, capital loss carryforward, swap investments, principal and/or interest of fixed income securities, investments in partnerships, foreign currency transactions, net operating loss, and investments in commodity subsidiaries. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Excess of distributions
over net investment
income ($)
Accumulated
net realized
(loss) ($)
Paid in
capital ($)
(12,787,144) 13,021,494 (234,350)
Net investment income (loss) and net realized gains (losses), as disclosed in the Consolidated Statement of Operations, and net assets were not affected by this reclassification.

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $2,400,327,810 and $2,044,096,062, respectively, for the year ended May 31, 2020, of which $2,087,722,061 and $1,918,275,018, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Consolidated Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests significantly in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Consolidated Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares

May 31, 2020
with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended May 31, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Consolidated Statement of Operations. This agreement expires annually in December unless extended or renewed.
For the year ended May 31, 2020, the Fund’s borrowing activity was as follows:
Average loan
balance ($)
Weighted average
interest rate (%)
Days
outstanding
500,000 2.09 2
Interest expense incurred by the Fund is recorded as a line of credit interest expense in the Consolidated Statement of Operations. The Fund had no outstanding borrowings at May 31, 2020.
Note 9. Significant risks
Alternative strategies investment risk
An investment in alternative investment strategies (Alternative Strategies) involves risks, which may be significant. Alternative Strategies may include strategies, instruments or other assets, such as derivatives, that seek investment returns uncorrelated with the broad equity and fixed income/debt markets, as well as those providing exposure to other markets (such as commodity markets), including but not limited to absolute (positive) return strategies. Alternative Strategies may fail to achieve their desired performance, market or other exposure, or their returns (or lack thereof) may be more correlated with the broad equity and/or fixed income/debt markets than was anticipated, and the Fund may lose money.
Columbia Multi Strategy Alternatives Fund  | Annual Report 2020

Table of Contents
Notes to Consolidated Financial Statements  (continued)
May 31, 2020
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Leverage risk
Leverage occurs when the Fund increases its assets available for investment using borrowings, short sales, derivatives, or similar instruments or techniques. The use of leverage may produce volatility and may exaggerate changes in the NAV of Fund shares and in the return on the Fund’s portfolio, which may increase the risk that the Fund will lose more than it has invested. Because short sales involve borrowing securities and then selling them, the Fund’s short sales effectively leverage the Fund’s assets. The Fund’s assets that are used as collateral to secure the Fund’s obligations to return the securities sold short may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage can create an interest expense that may lower the Fund’s overall returns. Leverage presents the opportunity for increased net income and capital gains, but may also exaggerate the Fund’s volatility and risk of loss. There can be no guarantee that a leveraging strategy will be successful.
LIBOR replacement risk
The elimination of London Inter-Bank Offered Rate (LIBOR), among other "inter-bank offered" reference rates, may adversely affect the interest rates on, and value of, certain Fund investments for which the value is tied to LIBOR. The U.K. Financial Conduct Authority has announced that it intends to stop compelling or inducing banks to submit LIBOR rates after 2021. However, it remains unclear if LIBOR will continue to exist in its current, or a modified, form. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (SOFR), that is intended to replace U.S. dollar LIBOR. Markets are slowly developing in response to these new reference rates. Questions around liquidity impacted by these rates, and how to appropriately adjust these rates at the time of transition, remain a concern for the Fund. The effect of any changes to, or discontinuation of, LIBOR on the Fund will vary, and it is difficult to predict the full impact of the transition away from LIBOR on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted and market practices become settled.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity.

Notes to Consolidated Financial Statements  (continued)
May 31, 2020
Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Money market fund investment risk
An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. If the liquidity of a money market fund’s portfolio deteriorates below certain levels, the money market fund may suspend redemptions (i.e., impose a redemption gate) and thereby prevent the Fund from selling its investment in the money market fund or impose a fee of up to 2% on amounts the
Columbia Multi Strategy Alternatives Fund  | Annual Report 2020

Table of Contents
Notes to Consolidated Financial Statements  (continued)
May 31, 2020
Fund redeems from the money market fund (i.e., impose a liquidity fee). These measures may result in an investment loss or prohibit the Fund from redeeming shares when the Investment Manager would otherwise redeem shares. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion of such investment. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in derivatives. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds.
Mortgage- and other asset-backed securities risk
The value of any mortgage-backed and other asset-backed securities including collateralized debt obligations, if any, held by the Fund may be affected by, among other things, changes or perceived changes in: interest rates; factors concerning the interests in and structure of the issuer or the originator of the mortgages or other assets; the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements; or the market’s assessment of the quality of underlying assets. Payment of principal and interest on some mortgage-backed securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of a particular U.S. Government agency, authority, enterprise or instrumentality, and some, but not all, are also insured or guaranteed by the U.S. Government. Mortgage-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may entail greater risk than obligations guaranteed by the U.S. Government. Mortgage- and other asset-backed securities are subject to liquidity risk and prepayment risk. A decline or flattening of housing values may cause delinquencies in mortgages (especially sub-prime or non-prime mortgages) underlying mortgage-backed securities and thereby adversely affect the ability of the mortgage-backed securities issuer to make principal and/or interest payments to mortgage-backed securities holders, including the Fund. Rising or high interest rates tend to extend the duration of mortgage- and other asset-backed securities, making their prices more volatile and more sensitive to changes in interest rates.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At May 31, 2020, affiliated shareholders of record owned 98.5% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted below, there were no items requiring adjustment of the financial statements or additional disclosure.
The Fund’s Board of Trustees approved reverse stock splits of the issued and outstanding shares of the Fund (the Reverse Stock Split). This event does not affect the overall net assets of the class. The Reverse Stock Split is expected to occur in the second half of 2020.

Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Multi Strategy Alternatives Fund
Opinion on the Financial Statements
We have audited the accompanying consolidated statement of assets and liabilities, including the consolidated portfolio of investments, of Columbia Multi Strategy Alternatives Fund and its subsidiaries (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of May 31, 2020, the related consolidated statement of operations for the year ended May 31, 2020, the consolidated statement of changes in net assets for each of the two years in the period ended May 31, 2020, including the related notes, and the consolidated financial highlights for each of the five years in the period ended May 31, 2020 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended May 31, 2020 and the financial highlights for each of the five years in the period ended May 31, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our procedures included confirmation of securities owned as of May 31, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (Program). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the Committee). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

Manager Discussion of Fund Performance
For the 12-month period that ended May 31, 2020, the Fund’s Class A shares returned 6.26% excluding sales charges. The Fund underperformed its benchmark, the Russell 1000 Index, which returned 12.54% over the same time period. Growth-oriented securities, many of which pay no dividends, continued to dominate market leadership, and the Fund’s mandate to invest in dividend-paying equities left it unable to hold many of the top-performing stocks in the benchmark. Despite the Fund’s underperformance relative to the benchmark, the Fund substantially outperformed most other value-focused equity funds, finishing in the top 7% of its Morningstar category. Strong stock selection and a focus on quality and diversification helped the Fund’s performance during a highly-turbulent period for equities.
A year of unprecedented volatility for equity markets
Trade concerns weighed on equities early in the 12-month period that ended May 31, 2020, as relations between the U.S. and China worsened dramatically, leading to higher tariffs and heightened uncertainty about the growth outlook for the global economy. After more than 10 years without a rate cut, the U.S. Federal Reserve (Fed) implemented three successive quarter-point reductions in the federal funds target rate between July and October 2019. Equity performance nonetheless remained subdued during most of the first half of the period as trade negotiations had a mixed tone.
The second half of the period began on a more positive note, as the U.S. and China announced their "phase one" trade agreement in mid-December. Equities responded by advancing to record levels. However, the emergence of the COVID-19 pandemic caused an unprecedented rapid reversal in the stock market, as containment measures essentially brought the global economy to a halt. Equities moved sharply lower between mid-February and late-March 2020 as investors rotated out of risk assets. In response, the Fed cut short-term interest rates to zero and turned to emergency asset purchase and credit programs similar to those used during the financial crisis in 2008 and 2009, while Congress passed a $2.2 trillion stimulus package. These aggressive measures on the fiscal and monetary policy fronts helped stocks mount a strong recovery, leading to solid positive results over the full period.
Bonds generally underperformed equities for the 12-month period. The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of investment-grade bonds, returned 9.42%, while the S&P 500 Index, a broad measure of U.S. stock returns, gained 12.84% for the same period.
Contributors and detractors
On a sector basis, stock selection within the real estate, industrials, and utilities sectors contributed to the Fund’s performance relative to the benchmark. In real estate, positions in Digital Realty Trust, Inc. and Crown Castle International Corp. were standout performers. Digital Realty Trust owns data centers that enterprise customers use to manage their cloud computing operations, while Crown Castle owns cellular towers and leases space to wireless network providers and other digital communications users. Both real estate investment trusts benefited from favorable conditions in the information technology and communication services sectors. In industrials, the Fund’s lack of exposure to The Boeing Company and General Electric Company proved beneficial. Among utilities, we continued to focus on those companies that operate in jurisdictions in which we believed regulation was favorable and jurisdictions where utility companies were allowed to invest heavily and recoup expenditures through rate increases. These positions performed strongly during the period, highlighted by positive contributions from NextEra Energy, Inc. The Fund also benefited from not owning positions in Exelon Corporation and Duke Energy Corporation.
Conversely, stock selection within information technology was the primary detractor from performance relative to the benchmark. Specifically, the Fund’s strategic decision to maintain underweight allocations to Apple and Microsoft weighed on returns, as both stocks rose dramatically. Despite the Fund’s underweight relative to the benchmark, Apple and Microsoft remained among the 10 largest holdings in the Fund. Moreover, semiconductor equipment companies KLA Corp. and LAM Research Corp. were among the top individual stock contributors. Both companies benefited from greater demand for semiconductors in electronic devices, as LAM Research’s high-quality production lines and KLA’s testing equipment helped customers produce semiconductor chips more efficiently. Microprocessor chipmaker Intel Corp. also added to relative performance as it extended its addressable market beyond PCs to include servers, which were in high demand.

Manager Discussion of Fund Performance  (continued)
Similarly, the health care sector also weighed on relative performance, as the Fund was unable to hold small, non-dividend paying biotechnology stocks, many of which outperformed during the period. Overweight allocations to pharmaceutical companies Merck & Co., Inc. and Pfizer, Inc. also hurt returns, although the Fund’s position in Bristol-Myers Squibb Co. performed well as the company made strides toward integrating its operations with those of the recently acquired Celgene Corporation.
Finally, the Fund’s positioning in the financial and communication services sectors detracted from relative returns. Within financials, an overweight position in banks detracted from performance, most notably the Fund’s positions in U.S. Bancorp, Wells Fargo & Co., and Bank of America Corp. Sentiment with respect to the banking industry was negatively impacted as the economic outlook shifted toward a more recessionary view late in the period and the yield curve flattened. In addition, higher default rates raised concerns about dividend sustainability. Insurance company Chubb Ltd. was also a notable detractor, as investors worried about potential claim liability for business interruptions stemming from the COVID-19 pandemic. In communication services, the Fund’s lack of positions in non-dividend-paying stocks Facebook, Inc. and Alphabet Inc. detracted significantly from performance, as both companies performed well as investors focused on growth plays even during the late-period downturn.
At period’s end
Our disciplined management process prevented us from investing in some of the stocks that led market performance during the difficult market conditions that prevailed throughout much of the 12-month period. However, we continue to believe that our focus on maintaining a diversified portfolio of high-quality companies with strong free cash flows will serve our shareholders well over the long run.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Value securities may be unprofitable if the market fails to recognize their intrinsic worth or the portfolio manager misgauged that worth. Foreign investments subject the Fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. Dividend payments are not guaranteed and the amount, if any, can vary over time. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and net asset value. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. The Fund may invest significantly in issuers within a particular sector, which may be negatively affected by market, economic or other conditions, making the Fund more vulnerable to unfavorable developments in the sector. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties who contributed to the report.

These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Fair value measurements  (continued)
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Notes to Financial Statements
May 31, 2020
Note 1. Organization
Columbia Dividend Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus. Class V shares are available only to investors who received (and who continuously held) Class V shares in connection with previous fund reorganizations.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Equity securities listed on an exchange are valued at the closing price or last trade on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and asked prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.
Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
22 Columbia Dividend Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
May 31, 2020
Investments in open-end investment companies (other than ETFs), are valued at the latest net asset value reported by those companies as of the valuation time.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.

Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared and paid each calendar quarter. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.72% to 0.52% as the Fund’s net assets increase. The effective management services fee rate for the year ended May 31, 2020 was 0.55% of the Fund’s average daily net assets.

Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended May 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.13
Class V 0.13
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended May 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $2,566.

Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class C and Class R shares of the Fund, respectively.
Although the Fund may pay distribution and service fees up to a maximum annual rate of 0.35% of the Fund’s average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder liaison services), the Fund currently limits such fees to an aggregate fee of not more than 0.25% of the Fund’s average daily net assets attributable to Class A shares.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.50% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.25% for shareholder liaison services and up to 0.25% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.25% of the Fund’s average daily net assets attributable to Class V shares.
Sales charges (unaudited)

The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:

This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At May 31, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, post-October capital losses, re-characterization of distributions for investments, distribution reclassifications, and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Undistributed net
investment
income ($)
Accumulated
net realized
(loss) ($)
Paid in
capital ($)
(2,398,525) 2,398,525
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $8,485,974,814 and $2,342,561,391, respectively, for the year ended May 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.

Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund’s activity in the Interfund Program during the year ended May 31, 2020 was as follows:
Borrower or lender Average loan
balance ($)
Weighted average
interest rate (%)
Number of days
with outstanding loans
Lender 6,481,818 2.31 11
Interest income earned by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at May 31, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended May 31, 2020.
Note 9. Significant risks
Information technology sector risk
The Fund may be more susceptible to the particular risks that may affect companies in the information technology sector than if it were invested in a wider variety of companies in unrelated sectors. Companies in the information technology sectors are subject to certain risks, including the risk that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. Performance of such companies may be affected by factors including obtaining and protecting patents (or the failure to do so) and significant competitive pressures, including aggressive pricing of their products or services, new market entrants, competition for market share and short product cycles due to an accelerated rate of technological developments. Such competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may fall or fail to rise. In addition, many information technology sector companies have limited operating histories and prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the

29

Notes to Financial Statements  (continued)
May 31, 2020
Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Shareholder concentration risk
At May 31, 2020, two unaffiliated shareholders of record owned 32.3% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 13.1% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.

Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Dividend Income Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Dividend Income Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of May 31, 2020, the related statement of operations for the year ended May 31, 2020, the statement of changes in net assets for each of the two years in the period ended May 31, 2020, including the related notes, and the financial highlights for each of the five years in the period ended May 31, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended May 31, 2020 and the financial highlights for each of the five years in the period ended May 31, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of May 31, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (Program). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the Committee). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.

Percentages indicated are based upon total fixed income investments.
Bond ratings apply to the underlying holdings of the Fund and not the Fund itself and are divided into categories ranging from highest to lowest credit quality, determined by using the middle rating of Moody’s, S&P and Fitch, after dropping the highest and lowest available ratings. When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. When a bond is not rated by any rating agency, it is designated as “Not rated.” Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. The ratings assigned by credit rating agencies are but one of the considerations that the Investment Manager and/or Fund’s subadviser incorporates into its credit analysis process, along with such other issuer-specific factors as cash flows, capital structure and leverage ratios, ability to de-leverage (repay) through free cash flow, quality of management, market positioning and access to capital, as well as such security-specific factors as the terms of the security (e.g., interest rate and time to maturity) and the amount and type of any collateral.

4 Columbia High Yield Municipal Fund  | Annual Report 2020

Manager Discussion of Fund Performance
For the 12-month period that ended May 31, 2020, Class A shares of the Fund returned -3.41% excluding sales charges. During the same 12-month period, the Fund’s Blended Benchmark gained 0.24%, and the Bloomberg Barclays High Yield Municipal Bond Index returned -2.32%.
COVID-19 fueled high volatility in the tax-exempt market
Although high-yield municipal bonds posted a negative 12-month return, the asset class benefited from a relatively benign environment for the first three quarters of the reporting period. During this time, the U.S. economy continued its expansion, municipal yields marched toward new lows (as prices increased), and high-yield municipals extended their run of outperformance relative to investment-grade municipal bonds.
These favorable conditions quickly deteriorated in March of 2020 once the COVID-19 pandemic hit the United States. Municipal bonds experienced several record down days in mid-March 2020 as investors withdrew cash from municipal funds amid concerns about the virus’ potential financial impact on state and local governments. High-yield municipal bonds were hit particularly hard as their yield spread versus investment-grade debt, which had narrowed steadily over the past four years, rose sharply. (Rising yield spreads indicate underperformance.) Investor worries about the prospects of many bonds backed by economically sensitive revenues, such as sales taxes, hotels and air travel, further contributed to the withdrawals from high-yield municipal funds. Funds raised cash to meet these redemptions, causing high-yield bond prices to fall substantially more than those of investment-grade securities.
In late March 2020, the downturn in high-yield municipal bonds appeared to have ended and prices rallied with several days of record price gains. Investors seemed to have been encouraged by the U.S. Federal Reserve’s (Fed) decision to cut interest rates to zero and initiate a number of liquidity programs aimed at propping up financial assets. Congress also provided fiscal support with a stimulus package amounting to over $2 trillion. After pausing in April 2020, the market’s advance resumed in May as the Fed clarified potential support for municipal issuers and cash began to flow back into the market.
Despite this remarkable recovery, high-yield municipal bonds lagged investment-grade municipal bonds by a wide margin due to their underperformance in March 2020. For the full period, the -2.32% return for Bloomberg Barclays High Yield Municipal Bond Index was more than six percentage points behind the 3.98% gain for the investment-grade Bloomberg Barclays Municipal Bond Index.
Contributors and detractors
An overweight position in continuing care retirement communities, together with security selection in the sector, detracted from performance amid concerns about the vulnerability of the elderly to COVID-19. We remained comfortable with both the Fund’s allocation to the sector and the individual issues held in the portfolio at end of May 2020, but we sold some of the Fund’s positions in issuers that we believed had weaker fundamentals. Holdings in bonds with maturities of 25 years or longer also hurt relative results, as did selection in BBB and non-rated issues. Underweights in bonds rated AA and AAA, which outperformed as investors gravitated to higher quality assets, was an additional detractor. An underweight in special-tax bonds, together with selection in the special-tax and general obligation sectors, further weighed on Fund returns.
On the positive side, the Fund benefited from an underweight position and favorable security selection in hospitals, as well as an underweight in the industrial development revenue/pollution control revenue sector. Selection in 17- to 25-year maturities and charter schools also contributed to Fund returns. An overweighting in A rated issues, together with underweights in BB and non-rated debt, was a further plus.
A cautious but opportunistic approach
Coming into the period, the portfolio was focused on longer maturities due to the benign inflation environment and the positive slope to the municipal yield curve. This positioning reflected our belief that the incremental income on longer dated issues could augment returns over time. In addition, given the record length of the economic expansion and the apparent overvaluation of lower rated securities, we maintained an average credit quality above that of the Blended Benchmark.

Manager Discussion of Fund Performance  (continued)
As the economic effects of COVID-19 became evident, we reduced positions in vulnerable sectors such as airlines, airports, and other corporate-backed issues, as well as in health care, hotels, and bonds backed by sales taxes. We also selectively reduced allocations to the senior care, charter school and local general obligation sectors, based on our negative outlook for specific holdings in these areas. We redeployed the proceeds into what we viewed as higher quality hospitals, the essential transportation sector, and higher yielding tobacco issues.
We also rotated some of the proceeds into cash to be reinvested as higher yield spreads created what we believed to be opportunities. New York City’s Metropolitan Transportation Authority (MTA), the largest transit authority in the United States, is an example. Prior to the pandemic, the MTA’s longer maturity bonds typically traded approximately 40 basis points (0.4 percentage points) above the average yield on AAA rated municipal issues. As ridership plummeted through March and April 2020 due to COVID-19 and the ensuing economic shutdown across New York City, yields on the MTA’s outstanding bonds rose. As a result, a new issue by MTA in mid-May 2020 yielded nearly 330 basis points above the Blended Benchmark. Believing the MTA to be an essential service, we saw this as an opportunity to capture the higher yield.
We believed spreads on higher yielding municipals were still attractive by historical terms at the close of the period, despite their rally from late March 2020 onward. While we sought to capitalize on specific opportunities such as the MTA bonds, we remained cautious and selective due to continued uncertainty regarding the length and depth of the pandemic-induced recession. The Fund therefore maintained an above-average credit quality at the close of the period.
After the longest economic expansion on record, many states and municipalities entered the crisis in healthy financial positions via budget surpluses, ample rainy-day funds and reasonable budgetary flexibility. Valuations generally remained attractive relative to the long-term averages, but we believe the potential for further credit stress could lead to renewed volatility. As would be expected in such a large and diverse market, there are many issuers who we believe are well-positioned to weather the crisis and others whose challenges could be severe. In this environment, we remained focused on fundamental analysis and careful security selection to identify both risks and potential opportunities.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state, local or alternative minimum taxes. Market or other (e.g., interest rate) environments may adversely affect the liquidity of Fund investments, negatively impacting their price. Generally, the less liquid the market at the time the Fund sells a holding, the greater the risk of loss or decline of value to the Fund. See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at May 31, 2020:

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.
The Fund does not hold any significant investments (greater than one percent of net assets) categorized as Level 3.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

(a) In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.
(b) Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.
(c) Ratios include interest and fee expense related to the participation in certain inverse floater programs. If interest and fee expense related to the participation in certain inverse floater programs had been excluded, expenses would have been lower by 0.01%. Due to an equal increase in interest income from fixed rate municipal bonds held in trust, there is no impact on the Fund’s net assets, net asset value per share, total return or net investment income.
(d) Ratios include interfund lending expense which is less than 0.01%.
(e) The benefits derived from expense reductions had an impact of less than 0.01%.
(f) Expenses have been reduced due to a reimbursement of expenses overbilled by a third party. If the reimbursement had been excluded, the expense ratios would have been higher by the percentages shown for each class in the table below. All fee waivers and expense reimbursements by the Investment Manager and its affiliates were applied before giving effect to this third party reimbursement.

Notes to Financial Statements
May 31, 2020
Note 1. Organization
Columbia High Yield Municipal Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies (other than ETFs), are valued at the latest net asset value reported by those companies as of the valuation time.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
32 Columbia High Yield Municipal Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
May 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense

Notes to Financial Statements  (continued)
May 31, 2020
paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark and to manage exposure to movements in interest rates. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Effects of derivative transactions in the financial statements
The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; and the impact of derivative transactions over the period in the Statement of Operations, including realized and unrealized gains (losses). The derivative instrument schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.
The following table indicates the effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in the Statement of Operations for the year ended May 31, 2020:

Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Inverse floater program
The Fund may enter into transactions in which it transfers to trusts fixed rate municipal bonds in exchange for cash and residual interests in the trusts’ assets and cash flows, which are in the form of inverse floating rate securities. The trusts fund the purchases of the municipal bonds by issuing short-term floating rate notes to third parties. The residual interests held by the Fund (inverse floating rate securities) include the right of the Fund (i) to cause the holders of the short-term floating rate notes to tender their notes at par, and (ii) to transfer the municipal bonds from the trusts to the Fund, thereby collapsing the trusts. The municipal bonds transferred to the trusts, if any, remain in the Fund’s investments in securities and the related short-term floating rate notes are reflected as Fund liabilities under the caption “Short-term floating rate notes outstanding” in the Statement of Assets and Liabilities. The liability approximates the fair market value of the short-term notes. The notes issued by the trusts have interest rates that are multi-modal, which means that they can be reset to a new or different mode at the reset date (e.g., mode can be daily, weekly, monthly, or a fixed specific date) at the discretion of the holder of the inverse floating rate security. The floating rate note holders have the option to tender their notes to the trusts for redemption at par at each reset date. The income received by the inverse floating rate security holder varies inversely with the short-term rate paid to the floating rate note holders, and in most circumstances the inverse floating rate security holder bears substantially all of the underlying bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the underlying bond’s value. The inverse floating rate security holder will be subject to greater interest rate risk than if they were to hold the underlying bond because the interest rate is dependent on both the fixed coupon rate of the underlying bond and the short-term interest rate paid on the floating rate notes. The inverse floating rate security holder is also subject to the credit risk, liquidity risk and market risk associated with the underlying bond. The bonds held by the trusts serve as collateral for the short-term floating rate notes outstanding. Contractual maturities and interest rates of the municipal bonds held in trusts, if any, at May 31, 2020 are presented in the Portfolio of Investments. Interest and fee expense related to the short-term floating rate notes, which is accrued daily, is presented in the Statement of Operations and corresponds to an equal increase in interest income from the fixed rate municipal bonds held in trust. For the year ended May 31, 2020, the average value of short-term floating rate notes outstanding was $6,240,000 and the average interest rate and fees related to these short-term floating rate notes were 1.20% and 0.49%, respectively.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.

May 31, 2020
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.54% to 0.34% as the Fund’s net assets increase. The effective management services fee rate for the year ended May 31, 2020 was 0.54% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.

May 31, 2020
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended May 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.10
Advisor Class 0.10
Class C 0.10
Institutional Class 0.10
Institutional 2 Class 0.06
Institutional 3 Class 0.01
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended May 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $400.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.20% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.

May 31, 2020
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.65% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended May 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 209,988
Class C 1.00(b) 14,440
    
(a) This charge is imposed on certain investments of $500,000 or more if redeemed within 12 months after purchase.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  October 1, 2019

Class C 1.61 1.61
Institutional Class 0.66 0.66
Institutional 2 Class 0.62 0.61
Institutional 3 Class 0.57 0.56
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $362,235,114 and $398,152,215, respectively, for the year ended May 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund’s activity in the Interfund Program during the year ended May 31, 2020 was as follows:
Borrower or lender Average loan
balance ($)
Weighted average
interest rate (%)

Interest expense incurred by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at May 31, 2020.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended May 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
High-yield investments risk
Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called "high-yield" or "junk" bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments
40 Columbia High Yield Municipal Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
May 31, 2020
have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.

May 31, 2020
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Municipal securities risk
Securities issued by a particular state and its instrumentalities are subject to the risk of unfavorable developments in such state. A municipal security can be significantly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes in a particular state’s (state and its instrumentalities’) financial, economic or other condition and prospects.
Shareholder concentration risk
At May 31, 2020, two unaffiliated shareholders of record owned 44.9% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 15.3% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia High Yield Municipal Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia High Yield Municipal Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of May 31, 2020, the related statement of operations for the year ended May 31, 2020, the statement of changes in net assets for each of the two years in the period ended May 31, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended May 31, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of May 31, 2020 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (Program). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the Committee). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

Returns for Class A shares are shown with and without the maximum initial sales charge of 5.75%. Returns for Class C shares are shown with and without the 1.00% contingent deferred sales charge for the first year only. The Fund’s other share classes are not subject to sales charges and have limited eligibility. Please see the Fund’s prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each share class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of any fee waivers or reimbursements of Fund expenses by Columbia Management Investment Advisers, LLC and/or any of its affiliates. Absent these fee waivers or expense reimbursement arrangements, performance results would have been lower.
The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, maybe worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiathreadneedleus.com/investor/ or calling 800.345.6611.
* The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund’s oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable. Please visit columbiathreadneedleus.com/investor/investment-products/mutual-funds/appended-performance for more information.
The Modified Blended Benchmark consists of 60% MSCI ACWI (Net) and 40% Bloomberg Barclays Global Aggregate Bond Index.
The New Blended Benchmark consists of 60% MSCI ACWI (Net) Hedged to DM Currencies and 40% Bloomberg Barclays Global Aggregate Bond Hedged Index.
The Bloomberg Barclays Global Aggregate Bond Index is a broad-based benchmark that measures the global investment-grade fixed-rate debt markets.
The Bloomberg Barclays Global Aggregate Bond Hedged Index is an unmanaged index that is comprised of several other Bloomberg Barclays indexes that measure fixed income performance of regions around the world while hedging the currency back to the US dollar.
The MSCI ACWI (Net) is a free float-adjusted market capitalization index that is designed to measure equity market performance in the global developed and emerging markets. The MSCI ACWI (Net) captures large and mid cap representation across 23 developed markets and 26 emerging markets countries.
The MSCI ACWI (Net) Hedged to DM Currencies Index represents a close estimation of the performance that can be achieved by hedging the currency exposures of all developed market exposures of its parent index, the MSCI ACWI, to the USD, the “home” currency for the hedged index. The index is 100% hedged to the USD of developed market currencies by selling each foreign currency forward at the one-month Forward weight. The parent index is composed of large and mid cap stocks across 23 Developed Markets (DM) countries and 24 Emerging Markets (EM) countries.
The FTSE Three-Month U.S. Treasury Bill Index is an unmanaged index that represents the performance of three-month Treasury bills and reflects reinvestment of all distributions and changes in market prices.

(a) Percentages are based upon net assets. The percentages do not equal 100% due to the effects of leverage within the Fund’s portfolio. Leverage exists when the Fund purchases or sells an instrument or enters into a transaction without investing cash in an amount equal to the full economic exposure of the instrument or transaction. The Fund’s portfolio composition and its market exposure are subject to change. Inflation-Hedging Assets may include, but are not limited to, direct or indirect investments in commodity-related investments, including certain types of commodities-linked derivatives and notes, and U.S. and non-U.S. inflation-linked bonds. Interest Rate Assets generally include fixed-income securities issued by U.S. and non-U.S. governments. Spread Assets generally include any other fixed-income securities.

Manager Discussion of Fund Performance
For the 12-month period that ended May 31, 2020, the Fund’s Class A shares returned 5.41% excluding sales charges. While posting solid absolute gains, the Fund underperformed its Modified Blended Benchmark, which returned 5.99% for the same time period. The Fund also underperformed its New Blended Benchmark, which returned 7.12% for the time period. To compare, the FTSE Three-Month U.S. Treasury Bill Index returned 1.75% during the annual period. The Fund takes a risk-based approach to allocating assets across four primary segments of global capital markets.
During the annual period, the MSCI ACWI (Net) and the Bloomberg Barclays Global Aggregate Bond Index returned 5.43% and 5.59%, respectively, during the annual period. The MSCI ACWI Index (Net) Hedged to DM Currencies returned 6.34%, and the Bloomberg Barclays Global Aggregate Bond Hedged Index returned 7.02%.
Market state policy implementation drove results
The Fund uses a global risk allocation strategy and takes a flexible approach to allocating portfolio risk across multiple asset classes — equity securities, inflation-hedging assets, and fixed-income securities (generally consisting of fixed-income securities issued by governments, which are referred to as interest rate assets, and other fixed-income securities, which are referred to as spread assets). The Fund employs a market state classification process, based on multiple market-based indicators, to identify four distinct market environments and creates a policy or benchmark portfolio with a strategic risk allocation for each environment that is intended to generate attractive risk-adjusted returns in that environment. Allocations of risk to asset classes may differ significantly across market environments. While a global risk-balanced portfolio is what we expect the Fund to be in most often, other market states represent conditions when risk balancing may be less than ideal, and the portfolio can deviate from balance to improve risk-adjusted return potential for that environment. This could be to protect capital in a weakening market or to more fully participate when market conditions are considered favorable. Once a policy portfolio is established, the Fund then employs a tactical overlay process driven by the Columbia Global Asset Allocation Team’s Investment Strategy Outlook. During the annual period ended May 31, 2020, changes to the Fund’s risk allocation using this market state classification process contributed positively to performance relative to maintaining a static neutral state and compared to its Modified Blended Benchmark. However, the Fund underperformed the Modified Blended Benchmark due to diversifying the portfolio with out-of-benchmark positions that underperformed this Modified Blended Benchmark during these months.
The Fund’s absolute returns were positive during the annual period, though our tactical positioning overall was a modest detractor from the Fund’s relative performance during the annual period. Of the broad global asset classes to which the Fund allocates, its exposure to global government fixed-income securities and global equities contributed most positively, as the asset classes overall posted positive absolute returns. Additionally, the Fund’s allocations to spread assets, primarily investment-grade corporate bonds, high-yield bonds, mortgage-backed securities and emerging markets debt, boosted relative results. Conversely, exposure to commodities detracted most, as commodities sold off sharply amid severe supply and demand headwinds in the first several months of 2020.
Market state positioning reflected changing market conditions
The Fund uses an adaptive approach to re-allocate portfolio risk exposures as market conditions change in an effort to improve risk-adjusted returns. We believe no single portfolio is appropriate for all market environments and have identified four distinct market states: highly bullish, bullish, neutral and capital preservation. We expect the Fund to be in the neutral market state the majority of the time. The Fund made several deviations from the neutral market state during the annual period, moving into the bullish market state in August 2019 and into the highly bullish market state in October 2019, December 2019 and January 2020 when market-based indicators became more positive. The Fund subsequently shifted into the capital preservation market state in March 2020 and maintained that market state through May 2020. From a risk allocation perspective, the Fund in the neutral state allocates approximately 50% of the portfolio’s risk allocation in equities, with the remaining 50% of the portfolio’s risk allocation divided among the other asset classes. In the months when the Fund was in a bullish or highly bullish market state, the Fund increased its risk exposure to equities and decreased exposure to interest rates. In the months when the Fund was in a capital preservation state, the Fund decreased risk exposure to equities and increased exposure to interest rates. With these changes, the Fund’s portfolio turnover rate for the 12-month period was 314%.

Manager Discussion of Fund Performance  (continued)
Many asset classes posted positive absolute returns and demonstrated relative calm during the first eight months of the annual period ended May 31, 2020, as waning recession fears, forecasts for improving global economic growth, a “Phase One” trade deal with China, and an accommodative U.S. Federal Reserve (Fed) helped bolster investor sentiment. U.S. equities achieved record highs in February 2020. Then, fears of the rippling effects of the global COVID-19 pandemic on the economy, on corporate earnings and more began to roil the markets in late February 2020. The sell-off within the U.S. equity markets was swift, with the S&P 500 Index recording its fastest 30% decline in history, taking only 22 trading days from the record high it had reached on February 19, 2020. Exacerbating matters was the plunging of the price of oil to its lowest level since 2002, as the world’s largest oil producers failed to agree on whether to reduce supply as demand collapsed. In response, most central banks and governments took extraordinary measures in an effort to limit financial market stress, mitigate the economic fallout and cushion household and business income. The U.S. Federal Reserve cut interest rates to near zero, committed to buy an unlimited amount of U.S. Treasury and agency mortgage-backed securities and increased the scope of its asset purchase program. On the fiscal front, the U.S. government enacted a more than $2 trillion relief bill, unleashing a massive stimulus plan to stem economic damage.
Following the steep drop, the S& P 500 Index surged to its best weekly gain in 11 years at the end of March 2020 on the unprecedented fiscal and monetary emergency stimulus. In April 2020, U.S. equities then enjoyed their largest monthly gain since January 1987 amid the policy momentum, improved credit market functioning, signs U.S. COVID-19 infections had plateaued and indications some states would soon begin to ease lockdown measures. The U.S. equity market rebound continued in May 2020 on the gradual re-opening of the U.S. to a new normal, even as macroeconomic data indicated measures to stem the spread of COVID-19, including quarantined consumers and business closures, took a severe toll on the U.S. economy. The S&P 500 Index was up 36.06% from its low on March 23 through the end of May 2020.
Against this backdrop, there was a meaningful difference in performance between value and growth equities across the capitalization spectrum within the U.S. equity market. For example, among large cap stocks, the Russell 1000 Growth Index posted a return of 26.25% as compared to the -1.64% return of the Russell 1000 Value Index for the annual period. International equities were weaker overall than U.S. equities. The MSCI EAFE Index (Net), representing developed international market equities, posted a return of -2.81% for the annual period, and emerging markets equities struggled even more, with the MSCI Emerging Markets Index (Net) generating a return of -4.39%.
As U.S. equities sold off in the first quarter of 2020, investors engaged in a “flight to quality,” and the fixed-income asset class overall outperformed equities both for the first quarter and for the 12-month period ended May 31, 2020. The Bloomberg Barclays U.S. Aggregate Bond Index, a broad proxy for the U.S. fixed-income market, posted a return of 9.42%, led by U.S. Treasuries. The Bloomberg Barclays Treasury Index rose 11.36% for the annual period, among the best returns in the capital markets. Securitized bonds and investment-grade corporate bonds also posted strong returns, as measured by the 6.46% return of the Bloomberg Barclays Securitized Index and the 10.03% return of the Bloomberg Barclays U.S. Corporate Bond Index, respectively. In contrast, high-yield corporate bonds and emerging markets bonds, like equities, posted positive absolute returns through the first eight months of the annual period but then experienced significant losses amid the COVID-19-driven turmoil. For the annual period overall, high-yield corporate bonds, as measured by the Bloomberg Barclays U.S. Corporate High Yield Index, returned 1.32%, and emerging markets bonds, as measured by the JPMorgan Emerging Markets Bond Index-Global, returned 1.65%. The Bloomberg Barclays Global Aggregate Bond Index, a broad proxy for the global fixed-income market, returned 5.59% for the annual period.
Returns of inflation-hedging asset classes were mixed during the annual period. Real estate investment trusts (REITs) posted strong returns for the first eight months of the annual period but subsequently gave back those gains and more, resulting in a -14.55% return for the FTSE Nareit Equity REITs index for the annual period. Commodities were also sharply negative. Oil prices, industrial metals and agricultural commodities fell on plummeting demand, even as gold prices rose with investors flocking to perceived safe-haven assets. The Bloomberg Commodity Index posted a -17.05% return for the annual period. Conversely, global inflation-linked bonds, as measured by the Bloomberg Barclays Global Inflation Linked Bond Index (unhedged), returned 5.73% during the annual period.

Derivative positions in the Fund
During the annual period, the Fund used futures (including bond, currency, equity, index and interest rate futures), currency forwards, options and swaps (including credit default, credit default swap index, interest rate and total return swaps). The Fund used derivatives for both hedging and non-hedging purposes, including, for example, seeking to enhance returns or as a substitute for a position in an underlying asset. The Fund also used derivatives to manage its overall risk exposure and to obtain leverage (market exposure in excess of the Fund’s assets) within certain asset classes and during certain market environments in seeking to maintain attractive expected risk-adjusted returns while adhering to the Fund’s risk allocation framework. The use of derivatives allows the Fund to pursue its risk allocation objectives. On a stand-alone basis, the use of these derivatives had a positive impact on the Fund’s return.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The Fund’s investment in other funds subjects it to the investment performance (positive or negative), risks and expenses of these underlying funds. Asset allocation does not assure a profit or protect against loss. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in Fund value. Commodity investments may be affected by the overall market and industry- and commodity-specific factors, and may be more volatile and less liquid than other investments. Short positions (where the underlying asset is not owned) can create unlimited risk. International investing involves certain risks and volatility due to potential political, economic or currency instabilities and different financial and accounting standards. Risks are enhanced for emerging market issuers. Investment in or exposure to foreign currencies subjects the Fund to currency fluctuation and risk of loss. Investments in small- and mid-cap companies involve risks and volatility greater than investments in larger, more established companies. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Interest payments on inflation-protected securities may be more volatile than interest paid on ordinary bonds. In periods of deflation, these securities provide no income. As a non-diversified fund, fewer investments could have a greater effect on performance. Investments selected using quantitative methods may perform differently from the market as a whole and may not enable the Fund to achieve its objective. Market or other (e.g., interest rate) environments may adversely affect the liquidity of fund investments, negatively impacting their price. Generally, the less liquid the market at the time the Fund sells a holding, the greater the risk of loss or decline of value to the Fund. See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

* Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Note 1. Organization
Columbia Adaptive Risk Allocation Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
The Fund invests significantly in shares of affiliated funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), or its affiliates as well as third-party advised (unaffiliated) funds, including exchange-traded funds (collectively, Underlying Funds).
For information on the Underlying Funds, please refer to the Fund’s current prospectus and the prospectuses of the Underlying Funds, which are available, free of charge, from the Securities and Exchange Commission website at www.sec.gov.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Equity securities listed on an exchange are valued at the closing price or last trade on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and asked prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.

Notes to Financial Statements  (continued)
May 31, 2020
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.
Investments in the Underlying Funds (other than ETFs) are valued at the latest net asset value reported by those companies as of the valuation time.
Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or

terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Forward foreign currency exchange contracts
Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund’s securities, to shift foreign currency exposure back to U.S. dollars, to shift U.S. dollar exposure to achieve a representative weighted mix of major currencies in its benchmark and to generate total return through long and short positions versus the U.S. dollar. These instruments may be used for other purposes in future periods.
The values of forward foreign currency exchange contracts fluctuate daily with changes in foreign currency exchange rates. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the forward foreign currency exchange contract is closed or expires. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without delivery of foreign currency.
The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund’s portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark, to manage exposure to movements in interest rates and to maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Options contracts
Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund [purchased and wrote] option contracts [to produce incremental earnings, to decrease the Fund’s exposure to equity market risk and to increase return on investments, to protect gains, to facilitate buying and selling of securities for investments, to hedge the security exposure associated with some or all of the Fund’s securities, to synthetically add or subtract principal exposure to a security, to manage exposure to fluctuations in interest rates and to hedge the fair value of the Fund’s investments]. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain over-the-counter option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.
Columbia Adaptive Risk Allocation Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
May 31, 2020
Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.
For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.
Swap contracts
Swap contracts are negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the CCP in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Portfolio of Investments and cash deposited is recorded in the Statement of Assets and Liabilities as margin deposits. Unlike a bilateral swap contract, for centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the CCP stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Statement of Assets and Liabilities.
Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the FCM or CCP may not fulfill its obligation under the contract.
Credit default swap contracts
The Fund entered into credit default swap contracts to increase or decrease its credit exposure to an index and to manage credit risk exposure. These instruments may be used for other purposes in future periods. Credit default swap contracts are agreements in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are generally defined as bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.
As the purchaser of a credit default swap contract, the Fund purchases protection by paying a periodic interest rate on the notional amount to the counterparty. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized loss upon payment. If a credit event as specified in the contract occurs, the Fund may have the option either to deliver the reference obligation to the seller in exchange for a cash payment of its par amount,
32 Columbia Adaptive Risk Allocation Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
May 31, 2020
or to receive a net cash settlement equal to the par amount less an agreed-upon value of the reference obligation as of the date of the credit event. The difference between the value of the obligation or cash delivered and the notional amount received will be recorded as a realized gain (loss).
As the seller of a credit default swap contract, the Fund sells protection to a buyer and will generally receive a periodic interest rate on a notional amount. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized gain upon receipt of the payment. If a credit event as specified in the contract with the counterparty occurs, the Fund may either be required to accept the reference obligation from the buyer in exchange for a cash payment of its notional amount, or to pay the buyer a net cash settlement equal to the notional amount less an agreed-upon value of the reference obligation (recovery value) as of the date of the credit event. The difference between the value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Portfolio of Investments.
As a protection seller, the Fund bears the risk of loss from the credit events specified in the contract with the counterparty. For credit default swap contracts on credit indices, quoted market prices and resulting market values serve as an indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the contract.
Any upfront payments or receipts by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.
Credit default swap contracts can involve greater risks than if a fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk.
Interest rate swap contracts
The Fund entered into interest rate swap transactions which may include inflation rate swap contracts to manage interest rate and market risk exposure to produce incremental earnings, to gain exposure to or protect itself from market rate changes and to synthetically add or subtract principal exposure to a market. These instruments may be used for other purposes in future periods. An interest rate swap is an agreement between two parties where there are two flows and payments are made between the two counterparties and the payments are dependent upon changes in an interest rate, inflation rate or inflation index calculated on a nominal amount. Interest rate swaps are agreements between two parties that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future, based on a predetermined, specified notional amount. Certain interest rate swaps are considered forward-starting, whereby the accrual for the exchange of cash flows does not begin until a specified date in the future. The net cash flow for a standard interest rate swap transaction is generally the difference between a floating market interest rate versus a fixed interest rate.
Interest rate swaps are valued daily and unrealized appreciation (depreciation) is recorded. Certain interest rate swaps may accrue periodic interest on a daily basis as a component of unrealized appreciation (depreciation); the Fund will realize a gain or loss upon the payment or receipt of accrued interest. The Fund will realize a gain or a loss when the interest rate swap is terminated.

Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.

Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
To be announced securities
The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.
In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.
Treasury inflation protected securities
The Fund may invest in treasury inflation protected securities (TIPS). The principal amount of TIPS is adjusted periodically and is increased for inflation or decreased for deflation based on a monthly published index. These adjustments are recorded as interest income in the Statement of Operations. Coupon payments are based on the adjusted principal at the time the interest is paid.
Offsetting of assets and liabilities

Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Income and capital gain distributions from the Underlying Funds, if any, are recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to shareholders
Distributions from net investment income, if any, are declared and paid annually. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is a blend of (i) a fee that declines from 0.06% to 0.03%, depending on asset levels, on assets invested in affiliated mutual funds, exchange-traded funds and closed-end funds that pay an investment advisory fee to the Investment Manager, (ii) a fee that declines from 0.16% to 0.13%, depending on asset levels, on assets invested in exchange-traded funds and mutual funds that are not managed by the Investment Manager or its affiliates and (iii) a fee that declines from 0.76% to 0.63%, depending on asset levels, on assets invested in securities, instruments and other assets not described above, including affiliated mutual funds, exchange-traded funds and closed-end funds advised by the Investment Manager that do not pay an investment advisory fee, third party closed-end funds, derivatives and individual securities. The effective management services fee rate for the year ended May 31, 2020 was 0.68% of the Fund’s average daily net assets.
In addition to the fees and expenses which the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of the Underlying Funds (also referred to as "acquired funds") in which the Fund invests. Because the Underlying Funds have varied expense and fee levels and the Fund may own different proportions of Underlying Funds at different times, the amount of fees and expenses incurred indirectly by the Fund will vary.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transactions with affiliates
For the year ended May 31, 2020, the Fund engaged in purchase and/or sale transactions with affiliates and/or accounts that have a common investment manager (or affiliated investment managers), common directors/trustees, and/or common officers. Those purchase and sale transactions complied with provisions of Rule 17a-7 under the 1940 Act and were $0 and $508,364, respectively. The sale transactions resulted in a net realized gain of $12,184.

Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended May 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.05
Advisor Class 0.05
Class C 0.05
Institutional Class 0.05
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.05
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended May 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $20.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class C and Class R shares of the Fund, respectively.
Although the Fund may pay distribution and service fees up to a maximum annual rate of 0.35% of the Fund’s average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder liaison services), the Fund currently limits such fees to an aggregate fee of not more than 0.25% of the Fund’s average daily net assets attributable to Class A shares.

(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, including indirect expenses of the Underlying Funds, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At May 31, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, tax straddles, post-October capital losses, re-characterization of distributions for investments, swap investments, principal and/or interest of fixed income securities, and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $6,560,704,457 and $6,308,218,960, respectively, for the year ended May 31, 2020, of which $4,907,873,187 and $4,614,516,722, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended May 31, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended May 31, 2020.
Note 9. Significant risks
Commodity-related investment risk
The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include demand for the commodity, weather, embargoes, tariffs, and economic health, political, international, regulatory and other developments. Exposure to commodities and commodities markets may subject the value of the Fund’s investments to greater volatility than other types of investments. Commodities investments
42 Columbia Adaptive Risk Allocation Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
May 31, 2020
may also subject the Fund to counterparty risk and liquidity risk. The Fund may make commodity-related investments through one or more wholly-owned subsidiaries organized outside the U.S. that are generally not subject to U.S. laws (including securities laws) and their protections.
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Foreign securities and emerging market countries risk
Investing in foreign securities may involve certain risks not typically associated with investing in U.S. securities, such as increased currency volatility and risks associated with political, regulatory, economic, social, diplomatic and other conditions or events occurring in the country or region, which may result in significant market volatility. In addition, certain foreign securities may not be as liquid as U.S. securities. Investing in emerging markets may increase these risks and expose the Fund to elevated risks associated with increased inflation, deflation or currency devaluation. To the extent that the Fund concentrates its investment exposure to any one or a few specific countries, the Fund will be particularly susceptible to the risks associated with the conditions, events or other factors impacting those countries or regions and may, therefore, have a greater risk than that of a fund that is more geographically diversified.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Leverage risk
Leverage occurs when the Fund increases its assets available for investment using borrowings, short sales, derivatives, or similar instruments or techniques. The use of leverage may produce volatility and may exaggerate changes in the NAV of Fund shares and in the return on the Fund’s portfolio, which may increase the risk that the Fund will lose more than it has invested. Because short sales involve borrowing securities and then selling them, the Fund’s short sales effectively leverage the Fund’s assets. The Fund’s assets that are used as collateral to secure the Fund’s obligations to return the securities sold short may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage can create an interest expense that may lower the Fund’s overall returns. Leverage presents the opportunity for increased net income and capital gains, but may also exaggerate the Fund’s volatility and risk of loss. There can be no guarantee that a leveraging strategy will be successful.

Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.

May 31, 2020
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At May 31, 2020, affiliated shareholders of record owned 87.9% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Adaptive Risk Allocation Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Adaptive Risk Allocation Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of May 31, 2020, the related statement of operations for the year ended May 31, 2020, the statement of changes in net assets for each of the two years in the period ended May 31, 2020, including the related notes, and the financial highlights for each of the five years in the period ended May 31, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended May 31, 2020 and the financial highlights for each of the five years in the period ended May 31, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of May 31, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (Program). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the Committee). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee is required to pre-approve the engagement of the

registrant's independent auditors to provide audit and non-audit services to the registrant and non-audit services to its investment adviser (excluding any sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser (the "Adviser") or any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (a "Control Affiliate") if the engagement relates directly to the operations and financial reporting of the registrant.

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non-Audit Services (the "Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit-related, tax and other services to the registrant ("Fund Services"); (ii) non-audit services to the registrant's Adviser and any Control Affiliates, that relates directly to the operations and financial reporting of a Fund ("Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's Adviser and its Control Affiliates. A service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund's independent auditor; provided, however, that pre-approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC's rules are met.

Under the Policy, the Audit Committee may delegate pre-approval authority to any pre- designated member or members who are independent board members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre- approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre-approval of services performed by the independent auditor may not be delegated to management.

 

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the types of Fund Services and Fund-related Adviser Services that are subject to specific pre- approval. This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre- approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of pre-approved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit Committee is in agreement with the specific types of services that the independent auditor will be permitted to perform and the projected fees for each service.

The Fund's Treasurer or other Fund officer shall report to the Audit Committee at each of its regular meetings regarding all Fund Services or Fund-related Adviser Services provided since the last such report was rendered, including a description of the services, by category, with forecasted fees for the annual reporting period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor, by category, with actual fees during the current reporting period.

*****

(e)(2) None, or 0%, of the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund or affiliated entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

(f)Not applicable.

(g)The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant during the fiscal years ended May 31, 2020 and May 31, 2019 are approximately as follows:

2020

2019

$229,500

$284,500

(h)The registrant's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to

 

paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

Item 5. Audit Committee of Listed Registrants.

Not applicable.

Overview and Statement

 

 

Item 2 of Form N-CSR, the form used by registered management investment companies to file certified annual and semi-annual shareholder reports, requires a registered management investment company to disclose:

Whether it has adopted a code of ethics that applies to the investment company's principal executive officer and senior financial officers and, if it has not adopted such a code of ethics, why it has not done so; and

Any amendments to, or waivers from, the code of ethics relating to such officers.

The Board of each Fund has adopted the following Code of Ethics for Principle Executive and Senior Financial Officers (the "Code"), which sets forth the ethical standards to which the Fund holds its principal executive officer and each of its senior financial officers.

This Code should be read and interpreted in conjunction with the Overview and Implementation of Compliance Program Policy.

Policy The Board of each Fund has adopted the Code in order to comply with applicable regulatory requirements as outlined below:

I.Covered Officers/Purpose of the Code

This Code applies to the Fund's Principal Executive Officer, Principal Financial Officer, and Principal Accounting Officer or Controller (the "Covered Officers") for the purpose of promoting:

Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

Full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the SEC, and in other public communications made by the Fund;

Compliance with applicable laws and governmental rules and regulations;

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Proprietary and Confidential

Page 1 of 9

Page 1

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

Accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual or apparent conflicts of interest.

II.Administration of the Code

The Board has designated an individual to be primarily responsible for the administration of the Code (the "Code Officer"). In the absence of the Code Officer, his or her designee shall serve as the Code Officer, but only on a temporary basis.

The Board has designated a person who meets the definition of a Chief Legal Officer (the "CLO") for purposes of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder as the Fund's CLO. The CLO of the Fund shall assist the Fund's Code

Officer in administration of this Code. The Code Officer, in consultation with the CLO, shall be responsible for applying this Code to specific situations (in consultation with Fund counsel, where appropriate) and has the authority to interpret this Code in any particular situation.

III.Managing Conflicts of Interest

A "conflict of interest" occurs when a Covered Officer's personal interest interferes with the interests of, or his or her service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of the Covered Officer's position with the Fund. Certain provisions in the 1940 Act and the rules and regulations thereunder and the Advisers Act and the rules and regulations thereunder govern certain conflicts of interest that arise out of the relationships between Covered Officers and the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. The Fund's and its Adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of those provisions. This Code does not, and is not intended to, repeat or replace those programs and procedures, and conduct that is consistent with such programs and procedures falls outside of the parameters of this Code.

Although they do not typically present an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationships between the Fund and, as applicable, its Adviser, administrator, principal underwriter, pricing and bookkeeping agent and/or transfer agent (each, a "Primary Service Provider") of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund or for a Primary Service Provider, or for both), be involved in establishing policies and implementing decisions that will have different effects on the Primary

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

Service Providers and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationships between the Fund and the Primary Service Providers and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. In addition, it is recognized by the Board of the Fund that the Covered Officers also may be officers or employees of one or more other investment companies or organizations affiliated with the sponsor of the Fund covered by other similar codes and that the codes of ethics of those other investment companies or organizations will apply to the Covered Officers acting in such capacities for such other investment companies.

This Code covers general conflicts of interest and other issues applicable to the Funds under the Sarbanes-Oxley Act of 2002. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interests of the Fund. Certain examples of such conflicts of interest follow.

Each Covered Officer must:

Not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer, or a member of his or her family, would knowingly benefit personally to the detriment of the Fund;

Not knowingly cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer, or a member of his or her family, rather than the benefit of the Fund;

Not use material non-public knowledge of portfolio transactions made or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions; and

Report at least annually (or more frequently, as appropriate) known affiliations or other relationships that may give rise to conflicts of interest with respect to the Fund.

If a Covered Officer believes that he or she has a potential conflict of interest that is likely to materially compromise his or her objectivity or his or her ability to perform the duties of his or her role as a Covered Officer, including a potential conflict of interest that arises out of his or her responsibilities as an officer or employee of one or more Primary Service Providers or other funds, he or she should consult with the Code Officer, the CLO, the Fund's outside counsel, or counsel to the Independent Board Members, as appropriate.

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Page 3

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

Examples of potential conflicts of interest that may materially compromise objectivity or ability to perform the duties of a Covered Officer and which the Covered Officer should consider discussing with the Code Officer or other appropriate person include:

Service as a director on the board of a public or private company or service as a public official;

The receipt of a non-de minimus gift when the gift is in relation to doing business directly or indirectly with the Fund;

The receipt of entertainment from any company with which the Fund has current or prospective business dealings, unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

An ownership interest in, or any consulting or employment relationship with, any of the Fund's service providers, other than the Primary Service Providers or any affiliated person thereof; and

A direct or indirect material financial interest in commissions, transaction charges or spreads paid by the Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

IV. Disclosure and Compliance

It is the responsibility of each Covered Officer:

To familiarize himself or herself with the disclosure requirements generally applicable to the Fund, as well as the business and financial operations of the Fund;

To not knowingly misrepresent, and to not knowingly cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board, Legal Counsel, Independent Legal Counsel and auditors, and to governmental regulators and self-regulatory organizations;

To the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Fund and the Primary Service Providers with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

To adhere to and, within his or her area of responsibility, promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed.

V.Reporting and Accountability by Covered Officers Each Covered Officer must:

Upon adoption of the Code or becoming a Covered Officer, acknowledge in writing to the Fund's Board that he or she has received, read and understands the Code, using the form attached as Appendix A hereto;

Annually thereafter acknowledge in writing to the Fund's Board that he or she has received and read the Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix B hereto;

Not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith; and

Notify the Code Officer promptly if he or she knows of any violation, or of conduct that reasonably could be expected to be or result in a violation, of this Code. Failure to do so is a violation of this Code.

The Fund will follow the policy set forth below in investigating and enforcing this Code:

The Code Officer will endeavor to take all appropriate action to investigate any potential violation reported to him or her;

If, after such investigation, the Code Officer believes that no violation has occurred, the Code Officer will so notify the person(s) reporting the potential violation, and no further action is required;

Any matter that the Code Officer, upon consultation with the CLO, believes is a violation will be reported by the Code Officer or the CLO to the Fund's Audit

Committee;

The Fund's Audit Committee will be responsible for granting waivers, as appropriate; and

This Code and any changes to or waivers of the Code will, to the extent required, be disclosed as provided by SEC rules.

VI. Other Policies

This Code shall be the sole code of ethics adopted by the Fund for the purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered management investment companies thereunder. Insofar as other policies or procedures of the Fund or the Fund's Primary Service Providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Fund's and its Adviser's and principal underwriter's codes of ethics under Rule 17j-1 under the 1940 Act and the more detailed policies and procedures of the
